i am trying to use the dell wyse usb imaging tool version 3.0 which if im not mistaken is the newest version. when i plug my usb device into the machine i am able to see the usb in device manager, file explorer and disk managment. i have formatted it multiple time to nfts, the drive shows available when i hit the usb drives button on the bottom of the imaging tool on the left hand side, but when i select the drop down box to select the drive it not showing a usb drive. i have wiped the disk off the usb drive, created new partitions, deleted them , created new volumes, changed disk assignment letters, still not showing in the drop down for me to select on the imaging tool.
Explore to the root of your USB key and navigate to the image directory. Do the contents match up with the image you originally selected? If not, copy over the additional files and try again.
I was able to image a 5060 yesterday using the 3.0.0 version of the tool with a FAT32 key. Boot mode must be set to "Both", USB Boot set to Enabled. It may be necessary to disable secure boot to do this.
A bit of an old post so I am not sure if you resolved it yet.
I have seen this sometimes and the resolution is to change the drive letter of the USB drive to A: or B:
In addition USB tool 3.1 is now the current release.
So far I have tried the 3.1.0 version, changing drive letters, and different formatting for the USB in NTFS or exFAT (64GB since the drives are 32GB on the newer W10 thin clients). Also no antivirus to get in the way.
